RUG-PRINTING iviAoHINE.

Application filed November 16,1921. A.Seriali No. 515,485.l

To all whom t may conce/m:

Be it known that I, J OHN TAMBERLIN, a citizen of the United States', residing at Philadelphia, '1n the countyfof -Philadelphia and State of Pennsylvania, have invented certain Improvements 'in Rug-Printing Machines, of which thefollowing is a specification.

The improvements of this invention are designed more particularly for printingv rugs such as predetermined lengths of linoleuln or other floor coverings having designs provided With rectangular borders.

The improvements are adapted to be applied 'to usual types of block printing ma'- chines in which an intermittently movable carrier mechanism ltranslates a fabric step by step over a bed and under printing blocks or heads that are reciprocated in predetermined relation, to impress their particular congurations upon the fabric during the intervals between its `movements and thus produce the desired pattern or design thereon.

The invention is characterized by its improved means for regulating the operations of the printing heads by a master controller, thereby timing the movements of the heads in predetermined relation and regulating the lengths of thedesign or pattern of the respective rugs.

In the accompanyingdrawings, Fig. l is a broken side elevation of the forward end of a printing machine provided With my improvements, Fig. 2 is a broken lside ele-v vation of the rear end ofthe same machine; Fig. 3 is a side elevation of a detail for stopping the operation of the heads; Fig.. 4 is a broken side view and Fig. `5 is a transverse sectional vieu7 of means for controlling the operations of the blocks for printing intermediate sections of the design vor pattern; Fig. 6 is a broken sideview and Fig. 7 is a transverse sectional. view of means for controlling the operations of the blocks for printing the end sections of the design or pattern;A Fig. 8 is a brokenside View and Fig. 9 is a transverse sectional view of the master block Vcontrolling mechanism, and 10 is a diagrammatic view lof a section .of fam-aaa ,rection," so as anism, f j I l The machine shovvn in the dravvin'gs,"by

Way of illustrating an application of my improvements, rcomprises the frame 1 having ptedy tobe printed by the I journalled'therein the shafts@ andl 3 on which are fixed the respective Wheels 4 and 1 5 for carrying the pin belts 6, the latter engaging and vcarrying the fabric 7. overV the bed 8. Gam bars V9, provided with the notches 1 0, are reciprocated on the supporting rollers 'lland Vbeneath the guiderollers 12 journalled in the frameythe movement `being, edected by the rod'13 Which is connectedwith the bars and actuated bythe Veccentric 14 on the Wheel'il j'ournalled in the frame and driven'in any suitable man-- nei'. Racks'lG, Xe'd to the barst), rock the gears 1'1" on the. shaft 3' and oscillate the paWls 18 lined tothe gears, thev paWls acting upon the ratchet Wheels 19" Xed on the shaft. One of the racks reciprocates below the Vaxis of the shaft 3, 'and the other rack (not shown) reciprocates above the axis of the shaft 3; the teeth ofthe respective ratchet Wheels 19 being so arranged relatively to one another that one rack, through its paWl and ratchet Wheel, rotates the shaft one step upon the movement of the bars 9 in one direction and the other.V rack,`

through -its -pavvl and ratchet Wheel, rotates vthe shaft another step upon the movement of 'the bars 9 in the reverse dito operate' the carrier mechanism intermittently and advance 'the 'fabric step byv step. Slide bars or struts 20, 20 and 2O.,v movable vertically in the guides 21,' 21 and 21 carried by kthe frame, are provided at their lower endsl With the rollers 22, 22 and22, adaptedV to ride on the cam bars 9., and carryi atY their `upper endsthe printing heads or blocks 23, 23 and 23".vvhich are adapted toV fall into contact with the fabric on thebedS as the notches 10 reach their central position ivith relation to the rollers,the headsbeing elevated bythe movement ofthe bars frein such position.

Dogs 24, 24- and 24` fulcrumed on the frame, are 'adapted forengaging the respee tive bars 20, 20 and 20V, to hold them .in

their elevated positions, and connected inking mechanisms 25, 25 and 25 movable on tracks 26 apply the desired colors to the respective heads when elevated.

The foregoing construction, of ,known character, is provided, according to my invention, with the pins or spindles 27, 27 and 27 which are carried by the frame l and carry the respective lianged discs 28, 28 and 28 provided with the respective depending arms 29, 29 and 29 for rock`l ing them. A bar 30 has pivotally connected thereto the respective arms 29, 29 and 29, and also the oscillatory lever 3l carried by the pin 32, a cord or chain 33 passing from the rear end of the bar over the roller 34 to a weight 35 for drawing the bar Vback to a limited position. A pin 36 on the cam bar V9, in the movement of the latter in the direction of the arrow, strikes the arm 3l to 'move the bar 30 Vagainst the action of the weight'35; and a pin 3,7 on the bar 9, in the movement of the latter in the opposite direction, acts through a lever 38 on a stud 39 to move the bar 30 against the action of the weight. Thereby each movement of the bar l9 is `accompanied by a reciprocation of the 'bar 30 to Vadvance and retract or oscillate the corresponding arms 29, 29 and 29 to ygether with the respective discs 28, 28 and 28 through their complete arcs of moveinent.

K The' discs 28, 28 and 28" carry the respective actuating pawls 40, 40 and 40 (provided with disengaging lingers 4l, 41 and 4l projecting through the respective peiipheries of the discs) which engage the respective ratcliets 42, 42 and 42 jour AI'ialled on the respective spindles 27, 27 and 27 between the respective flanged discs 28 -and 43, 28 and 43, 28 and 43, the discs being `journalled on hubs of the respective ratchets. The discs 28 and 43 carry the respective dogs 44 and 44 for engaging the respective ratcliets 42 and 42, the dog 44 having a tail piece 44a for engaging a stud 43a on the disc 43. The teeth upon the respective ratchets 42 and 42 are arranged in three pairs, each pair being spaced from the adjacent pairs by peripheral section vof greater length than, the eiifective throw77 of the respective dogs 40 and 40, which dogs oscillate idly ovei' thesel peripheral ysections during the printing of the body portions of the rug and until teeth or the respective ratchet wheels are brought into the respective pat-hs of the dogs 40 and 40 by the actions of the respect-ive dogs 44 and 44. The dog 44 is normally held out ot' Yengagement with the teeth of the ratchet 42 lby the engagement with its tail 44a ot the stud 43a, the stud and tail being oscillated together by the respective discs 28 and 43 connected respectively with the rod 30 and being regulated thereby.

link 52. When, however, the head 23 is held in the elevated position the link does not oscillate the disc 43 and consequently the movement of the rod 30 will move the tail of the 'dog 44 out from under the stud 43a when the head 23 is in the elevated position.

Cams 45, 45 and 45, fixed to the respective ratchets 42, 42 and 42 areengage'd'by the respective lbearing devices 46, 46 and 46 on the longer and laterally extending arms of crank levers 47, 47 and 47 which are iulciiinied on the iiraine, the shorter arms of these levers being connected by the respective links 48, 48 and 48 with the respective dogs 24, 24 and 24. Hence when the high points of the cams 45, 45 and 45 engage the respective bearings 46, 45 and 46, the respective `dogs 24, 24 and 24 will be drawn by the intermediate devices into positions for engaging the respective studs 20, 20 and 20 to hold the corresponding heads 23, 23 and 23 in their elevated positions, and when the bearings of the crank levers engage the low points of the corresponding cams, the dogs willA be retracted to permit the corresponding heads t0 fall.

The cam 45 is provided with the consecutively numbered studs 49 corresponding 'i to the equally spaced teeth oil the ratchet- 42, this cain being turned in accordance with this gauge4 to any desired position with relation to the cams 45 and 45 and the4 relative operations or' the dogs 24, 24 and 24 together with the heads 23, 23 and 23 The bars 20, 20 and 20 are connected by the respective links 50, 50 and 50 pivote'd thereto with the longer arms of crank levers 5l, 5l and 5l which are ulcruiiied on the frame, the shorter arms of these levers being connected by links or rods 52, 52 and 52" with the respective arms 53, 53 and 53 on respective discs 43, 43., which are thereby rocked by the movements of the corresponding heads connected therewith.

A dog 54, pivoted to the frame, is adapted `for engaging a device 55 on the bar 30 for holding' the latter stationary iii the position to which it is moved bythe action of the stud 36 on the lever 3l or the action of the stud 37 on the lever 38, the parts actuated by the bar 30 being thus rendered inactive;

An oscillatory arm 56, Vprovided with the stud 57 adapted for engaging the top of the dog 54 on yeither side of its i'ulcruni, can be thrown so as to 'depress the dog to position for engaging the device when carried thereunder' by the rod 30, whereby the latter l is held "stationary, the position of the arm being reversed to elevate the dog so that it vis removed from the path of the device 55.

In the yoperation 'of the machine, the intermittent movements ofthe web or fabric 7 valternate with oscillations ofthe rods 30, and the printing heads are reciprocated by the cams 9 so as to engage the web 7 while it is at rest. The descent of the printing heads is substantially concurrent with the movement of the rods 30 toward the front (right) of the machine to move the control pawls 40, 40, 44 and 40 anticlockwise, and the elevation of the printing heads by the cams 9 -is substantially concurrent with the movement of the rods 30 toward the rear (left) of the machine to move the pawls clockwise.

If the ratchet wheel 42 ofthe master cam is provided'with seven teeth, as shown, the body-printing heads 23, 23 will normally reciprocate six times to each reciprocation of the border-printing heads'23; while if the ratchet wheel 42 of the master cam 45 is provided with some other number of teeth, the body-printing heads will reciprocate as many more times than the borderprinting heads as there are teeth on the ratchet wheel of the lmaster cam less one.y

The cycle of operations of the' machine may be conveniently considered as starting with the ratchet wheel 42 sopositioned that the part 46 lies at the foot of the protuberance on the cam 45, the printing head'sfall elevated and vthe rod 30v moved all the way toward the rear (left) of the machine; In this position of the mechanism, the border'- printing head 23 will be latched up, the part 46 of the lever 47 being engaged by one of the protuberancesv of the cam 45. rlhe ratchet wheel 42 is so disposed that the pawl'40 lies about midway between two pairs of teeth, and the pawl 44` has its tail 44a engaged' by' the stud 43@l on the disk 43. The head 23k will be unlatched,` the part 46 lyingin a depression between two protuberances of the cam'45. The ratchet wheel 42 is so-disposed that the-pawl 40 lies about midway between two pairs of teeth on the ratchet wheel, and the pawl 44 is held against movement by its connection with the latched head 23.

The descent of the body printing heads 23, 23, duev to the movement of the cams' 9, is accompanied by the movement of the -rod 30 toward tlieright, resultingy in the anticlockwise movement of the pawls 40, 40, 44 and 40. The descent* of the head 23 also acts, through the parts 50, 51,- 52, 53, and 43', to move the stud 43EL anti-clockwise in synchronism with the movement ofthe tail 44a of the pawl 44, thereby preventing engagement thereof with a tooth of the ratchet wheel 42 over which it is sus-` pended. lThe pawl 40 Iis thus placed in position to engage atooth of lthe ratchet wheel 42, but the pawls 40-and 40 slidey idly on the peripheral sections of the ratchet wheels-42 and42 between-two -of the pairs of teeth-v thereof. The borderprinting head vand *pawl 44 remain stationary.-

Upon the upward movement ofthe bodyprinting heads, the rod 3() is shifted 'to the effect upon the ratchet wheels 42 `and 42,

since the -p'awls 40 and 40 slide idly between the respective pairs of teeth thereof, the pawl 44 is held out of action by the synchronous movement therewith of the,

stud 43a, and the pawl 44 is held stationary by the latched head 23. Y l' During the next movement of the rod 30 to thevright, the head 23 is latched in the elevated position, to permit a border section to pass unprinted beneath it; the disk 43 and stud43a being thereby yheld against movement. moves the pawl-40 anti-clockwiseinto position for' engaging the next tooth of the The movement of therod 3() v ratchet42; moves the pawl 44 anti-clock-` wise so that its tail 44a is drawn outv from under the now 'stationary stud 43a and its head dropsvdo'wn into engagement with the`v rst tooth of a pairV on the ratchet wheel 42.' The pawls 40v and 40 vstill move idlyI between pairs of teeth on the respective ratchet wheels 42 and 4 and the pawl 44 still remains stationary. A

As the rod 30 again `mov`ves to the-left, it advances the pawl v40 clockwise to move the protuberance of the camA k45 from under the devicej46 of the lever '47, thereby unlatching thefhead 23; it advances the-pawl 44 clockwise so as to rotateI the ratchet 42 and bring the first toothof asucceeding pair 'of teethl into the path of movement of the pawl 40"; the cam 45 being therebyturned so that the device`46- lies near kthe -endof its supporting protuberance.

thereby Permitting the latter to rook and .v

nnlatoh the head 23". During these move- Inen-ts of; the rod 30, the Pavvl 44 s held stationary by its connection with the latehed head. 2.3,. Y v l l The reoiprooations of ther body-printing heads and the oscillations of tlile. rod k.d0Y is Continued until theVprotnberaneefo:the sono 4o again elevates the part 46 of the leven 4.7,

whenl the operations described r are repeated The operation. of: additional vprinting heads may be controlled in the sameonanner as Qontrol is eieotedjof the headseiiitheoperation described, whereby any desired mund ben of; colorsv Inlay be impressed. upon the body and borders of a rug.; c

Frorn the foregoing, it Will be understood that the reeiproeation,y or latching` of the rst printing heed isy positively controlled by the master @am 45,; the reoiproeation or late-hing of the second printing head is controlled through the aotion ,of the first printing head; the reoiproeation or latohing of the third printing head controlled through the notion of theseeondprinting head, and so on, so that an adjustment of the master oamalone Will regulate the actions of all ftheprinting heads in sequence. Hence if it is desired to make a longer rug than would be normally made Withthe use of the ratchet Wheel 42, thel pavvl 40 may be disengaged from the yratchet Wheel 42 (by operating the finger 41) to defer to any desired extentk the elevation of the lever 47 by the camy 45, thereby permitting the head 23 to make any desired number ofimpressions. Since the ato-tions4 of the remaining printing heads are controlled by the action of the head 23, the impressione of the additional heads Will follovv in properv sequence., Conversely, if it Yis desired to shorten a particular rug, the cam 45y may be manually advanced to cause the protuberance thereon to elevate the part 46 and rockthe lever 47, thereby latching the head 23 before the normal number of impressions have beenmade thereby; but the remaining heads, being regulated by the first head, will act at the proper time to complete the smaller rug.
